How to use the client-server API
|
||||
================================
|
||||
|
||||
If you haven't already, get a home server up and running on localhost:8080.
|
||||
|
||||
|
||||
Accounts
|
||||
========
|
||||
Before you can send and receive messages, you must register for an account. If
|
||||
you already have an account, you must login into it.
|
||||
|
||||
Registration
|
||||
------------
|
||||
The aim of registration is to get a user ID and access token which you will need
|
||||
when accessing other APIs.
|
||||
|
||||
curl -XPOST -d '{"user_id":"example", "password":"wordpass"}' "http://localhost:8080/matrix/client/api/v1/register"
|
||||
|
||||
{
|
||||
"access_token": "QGV4YW1wbGU6bG9jYWxob3N0.AqdSzFmFYrLrTmteXc",
|
||||
"home_server": "localhost",
|
||||
"user_id": "@example:localhost"
|
||||
}
|
||||
|
||||
NB: If a user ID is not specified, one will be randomly generated for you. If
|
||||
you do not specify a password, you will be unable to login to the account if you
|
||||
forget the access token.
|
||||
|
||||
Login
|
||||
-----
|
||||
The aim of login is to get an access token for your existing user ID.
|
||||
|
||||
curl -XGET "http://localhost:8080/matrix/client/api/v1/login"
|
||||
|
||||
{
|
||||
"type": "m.login.password"
|
||||
}
|
||||
|
||||
curl -XPOST -d '{"type":"m.login.password", "user":"example", "password":"wordpass"}' "http://localhost:8080/matrix/client/api/v1/login"
|
||||
|
||||
{
|
||||
"access_token": "QGV4YW1wbGU6bG9jYWxob3N0.vRDLTgxefmKWQEtgGd",
|
||||
"home_server": "localhost",
|
||||
"user_id": "@example:localhost"
|
||||
}
|
||||
|
||||
NB: Different home servers may implement different methods for logging in to an
|
||||
existing account. In order to check that you know how to login to this home
|
||||
server, you must perform a GET first and make sure you recognise the type. If
|
||||
you do not know how to login, you can GET /login/fallback which will return a
|
||||
basic webpage which you can use to login.
|
||||
|
||||
|
||||
Making rooms and sending messages
|
||||
=================================
|
||||
|
||||
Creating a room
|
||||
---------------
|
||||
If you want to send a message to someone, you have to be in a room with them. To
|
||||
create a room:
|
||||
|
||||
curl -XPOST -d '{"room_alias_name":"tutorial"}' "http://localhost:8080/matrix/client/api/v1/rooms?access_token=QGV4YW1wbGU6bG9jYWxob3N0.vRDLTgxefmKWQEtgGd"
|
||||
|
||||
{
|
||||
"room_alias": "#tutorial:localhost",
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost"
|
||||
}
|
||||
|
||||
The "room alias" is a human-readable string which can be shared with other users
|
||||
so they can join a room, rather than the room ID which is a randomly generated
|
||||
string. You can have multiple room aliases per room.
|
||||
|
||||
TODO(kegan): How to add/remove aliases from an existing room.
|
||||
|
||||
|
||||
Sending messages
|
||||
----------------
|
||||
You can now send messages to this room:
|
||||
|
||||
curl -XPUT -d '{"msgtype":"m.text", "body":"hello"}' "http://localhost:8080/matrix/client/api/v1/rooms/%21CvcvRuDYDzTOzfKKgh:localhost/messages/%40example%3Alocalhost/msgid1?access_token=QGV4YW1wbGU6bG9jYWxob3N0.vRDLTgxefmKWQEtgGd"
|
||||
|
||||
NB: There are no limitations to the types of messages which can be exchanged.
|
||||
The only requirement is that 'msgtype' is specified.
|
||||
|
||||
|
||||
Inviting and joining rooms
|
||||
==========================
|
||||
|
||||
Inviting a user to a room
|
||||
-------------------------
|
||||
You can directly invite a user to a room like so:
|
||||
|
||||
curl -XPUT -d '{"membership":"invite"}' "http://localhost:8080/matrix/client/api/v1/rooms/%21CvcvRuDYDzTOzfKKgh:localhost/members/%40myfriend%3Alocalhost/state?access_token=QGV4YW1wbGU6bG9jYWxob3N0.vRDLTgxefmKWQEtgGd"
|
||||
|
||||
This informs @myfriend:localhost of the room ID !CvcvRuDYDzTOzfKKgh:localhost
|
||||
and allows them to join the room.
|
||||
|
||||
Joining a room via an invite
|
||||
----------------------------
|
||||
If you receive an invite, you can join the room by changing the membership to
|
||||
join:
|
||||
|
||||
curl -XPUT -d '{"membership":"join"}' "http://localhost:8080/matrix/client/api/v1/rooms/%21CvcvRuDYDzTOzfKKgh:localhost/members/%40myfriend%3Alocalhost/state?access_token=QG15ZnJpZW5kOmxvY2FsaG9zdA...XKuGdVsovHmwMyDDvK"
|
||||
|
||||
NB: Only the person invited (@myfriend:localhost) can change the membership
|
||||
state to 'join'.
|
||||
|
||||
Joining a room via an alias
|
||||
---------------------------
|
||||
Alternatively, if you know the room alias for this room and the room config
|
||||
allows it, you can directly join a room via the alias:
|
||||
|
||||
curl -XPUT -d '{}' "http://localhost:8080/matrix/client/api/v1/join/%23tutorial%3Alocalhost?access_token=QG15ZnJpZW5kOmxvY2FsaG9zdA...XKuGdVsovHmwMyDDvK"
|
||||
|
||||
{
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost"
|
||||
}
|
||||
|
||||
You will need to use the room ID when sending messages, not the room alias.
|
||||
|
||||
Getting events
|
||||
==============
|
||||
An event is some interesting piece of data that a client may be interested in.
|
||||
It can be a message in a room, a room invite, etc. There are many different ways
|
||||
of getting events, depending on what state the client is in.
|
||||
|
||||
Getting all state
|
||||
-----------------
|
||||
If the client doesn't know any information on the rooms the user is
|
||||
invited/joined on, you can get all your state for all your rooms like so:
|
||||
|
||||
curl -XGET "http://localhost:8080/matrix/client/api/v1/im/sync?access_token=QG15ZnJpZW5kOmxvY2FsaG9zdA...XKuGdVsovHmwMyDDvK"
|
||||
|
||||
[
|
||||
{
|
||||
"membership": "join",
|
||||
"messages": {
|
||||
"chunk": [
|
||||
{
|
||||
"content": {
|
||||
"body": "@example:localhost joined the room.",
|
||||
"hsob_ts": 1408444664249,
|
||||
"membership": "join",
|
||||
"membership_source": "@example:localhost",
|
||||
"membership_target": "@example:localhost",
|
||||
"msgtype": "m.text"
|
||||
},
|
||||
"event_id": "lZjmmlrEvo",
|
||||
"msg_id": "m1408444664249",
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost",
|
||||
"type": "m.room.message",
|
||||
"user_id": "_homeserver_"
|
||||
},
|
||||
{
|
||||
"content": {
|
||||
"body": "hello",
|
||||
"hsob_ts": 1408445405672,
|
||||
"msgtype": "m.text"
|
||||
},
|
||||
"event_id": "BiBJqamISg",
|
||||
"msg_id": "msgid1",
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost",
|
||||
"type": "m.room.message",
|
||||
"user_id": "@example:localhost"
|
||||
},
|
||||
[...]
|
||||
{
|
||||
"content": {
|
||||
"body": "@myfriend:localhost joined the room.",
|
||||
"hsob_ts": 1408446501661,
|
||||
"membership": "join",
|
||||
"membership_source": "@myfriend:localhost",
|
||||
"membership_target": "@myfriend:localhost",
|
||||
"msgtype": "m.text"
|
||||
},
|
||||
"event_id": "IMmXbOzFAa",
|
||||
"msg_id": "m1408446501661",
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost",
|
||||
"type": "m.room.message",
|
||||
"user_id": "_homeserver_"
|
||||
}
|
||||
],
|
||||
"end": "20",
|
||||
"start": "0"
|
||||
},
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost"
|
||||
}
|
||||
]
|
||||
|
||||
This returns all the room IDs of rooms you are invited/joined on, as well as all
|
||||
of the messages and feedback for these rooms. This can be a LOT of data. You may
|
||||
just want the most recent message for each room. This can be done by applying
|
||||
pagination stream parameters to this request:
|
||||
|
||||
curl -XGET "http://localhost:8080/matrix/client/api/v1/im/sync?access_token=QG15ZnJpZW5kOmxvY2FsaG9zdA...XKuGdVsovHmwMyDDvK&from=END&to=START&limit=1"
|
||||
|
||||
[
|
||||
{
|
||||
"membership": "join",
|
||||
"messages": {
|
||||
"chunk": [
|
||||
{
|
||||
"content": {
|
||||
"body": "@myfriend:localhost joined the room.",
|
||||
"hsob_ts": 1408446501661,
|
||||
"membership": "join",
|
||||
"membership_source": "@myfriend:localhost",
|
||||
"membership_target": "@myfriend:localhost",
|
||||
"msgtype": "m.text"
|
||||
},
|
||||
"event_id": "IMmXbOzFAa",
|
||||
"msg_id": "m1408446501661",
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost",
|
||||
"type": "m.room.message",
|
||||
"user_id": "_homeserver_"
|
||||
}
|
||||
],
|
||||
"end": "20",
|
||||
"start": "21"
|
||||
},
|
||||
"room_id": "!CvcvRuDYDzTOzfKKgh:localhost"
|
||||
}
|
||||
]
|
||||
|
||||
Getting live state
|
||||
------------------
|
||||
Once you know which rooms the client has previously interacted with, you need to
|
||||
listen for incoming events. This can be done like so:
|
||||
|
||||
curl -XGET "http://localhost:8080/matrix/client/api/v1/events?access_token=QG15ZnJpZW5kOmxvY2FsaG9zdA...XKuGdVsovHmwMyDDvK&from=END"
|
||||
|
||||
{
|
||||
"chunk": [],
|
||||
"end": "215",
|
||||
"start": "215"
|
||||
}
|
||||
|
||||
This will block waiting for an incoming event, timing out after several seconds.
|
||||
A client should repeatedly make requests with the "from" query parameter with
|
||||
the value of "end" (in this case "215").
|
||||
|
||||
NB: The timeout can be changed by adding a "timeout" query parameter, which is
|
||||
in milliseconds. A timeout of 0 will not block.
